Here is a supposed video. Near the end you can see on the top left he raises his arm towards the officer but then they freeze the video.
This does not in anyway help the police's case unless they plan to release the whole video including the actual shooting later. Why freeze the video at that frame? Is it because they don't think we can handle the violence or are they hiding something? Just go ahead and release the whole video especially given the skepticism towards the cops. Most people following this case are big girls and boys. I don't think sensitive children are following the story.
